Configuring Switch ports in Campus Environments

Filed under: Router, Switching — ciscotips @ 12:13 am

Last week,  I saw my colleague doing something pretty weird and that kind of initiated me to write this tip which i thought was not a tip initally. Due to Large 6500 48 ports 10/100 cards deployment we need to assign vlans to probably different set of ports. I aw my colleague getting in to each interface and then configuring vlan with switchport access vlan command. I realised that most of us are not aware of cool cisco command to configure similar interfaces in a single go. Here is the command

In a large switch environment, to configure all or

multiple interfaces on a switch with the same configuration

parameters, do the following:

Switch(config)# interface range [ interface { port

range } ]

For example:

Switch(config)#interface range fastEthernet 0/1 – 30

To configure different ports with the same configuration:

Switch(config)#int range fa0/1 , fa0/12 , fa0/13



  1. Great tip. I also see this at work, but when I mentioned this tip to a fellow admin, the admin says that he likes to “touch” each interface. Well, I say go ahead and “touch” your interfaces all night long, while I touch a cold brew at the pub and my girl later. 🙂

    disables channeling and to enable spanning-tree portfast and the switchport nonegotiate command to turn off DTP negotiation packets.
